CTH Power Supply
Some of the features of this supply are:
- The HV supply uses a 3X voltage multiplier to make about 100VDC from 24VAC
- The LV supply has a high ripple rejection pre-regulator filter
- The heater supply uses a switching regulator for high efficiency, lower power dissipation
- The heater supply is switchable from 6.3V to 12.6V and can handle 600mA tubes
WARNING - 100VDC is significant high voltage. Every precaution for handling HV should be exercised.
